Buying Guide

Before you think of purchasing any of these products, it is vital to consider the following tips.

  1. Cooling Capacity: The first one is that ability of the fan to cool the bed. The better the fan cooling capacity, the higher the price of the bed fan. It is still important, however, to be cautious not to go for expensive bed fans in the name of hoping to secure the best cooling features.
  2. Complex Controls: The second one is the ease of use- there are great bed fans out there but, they operate using a technical module that may prove difficult when used by a beginner.
  3. Noisy?: The third aspect is to think about the amount of noise that the bed fans produces when it is active. Amazing and reliable ones will stay silent and perform their tasks effectively without the user noticing their presence while there are those that produce distracting sounds as soon as they turn on.
  4. Heating Feature?: Some of the more advanced fans offer heating capabilities.
  5. Remote control?: Some of them have remote controls so you can easily adjust the temperature as you’re preparing to drift off.
  6. Pricing: The final tip is the price of the whole product. As it has already come out clearly in the previous bits of this study, the higher the price, the more likely it is for the bed fan to offer quality services.

A bed fan is a product whose cardinal purpose is to provide an extra feel of coolness/warmth under the sheet when the user is asleep.

There are certain places in the world where it is extremely hot during the day and equally as cold during the night. It means that while the user could be struggling for a little breeze during the day, the idea is that when night comes, they will still need an extra fluff of warmth.

Safe Operation

When users begin raising questions such as is sleeping with a bed fan on bad for your health, it becomes clear that there are relevant tips that all users need to consider before beginning the use of this product.

The following will bring to light some of the most crucial tips that will help you stay cool at night and, still maintain the ideal functionality of your bed fan.

  1. The first point is to analyze the proximity of the bed fan to any source of water. It is the nature of all electronic devices to develop faulty mechanisms when they come into contact with any fluid, like water. The problem with sources of water, especially in residential places is that while the user may have taken all the necessary precautions to keep the water out, innocent children may have been playing with the tap and left it open. As a result, when it comes into contact with the bed fan, the negative impacts will not wait for long before showing up.
  2. The second point is about sleeping with the bed fan on at night. Health experts warn that allowing the bed fan to keep blowing in air to keep you warm will increase the tendencies of your skin to lose air, a condition that makes the skin appear pale. Deprivation of enough air from the skin will definitely affect the normal functioning of the body of the user of the bed fan. If the air goes own blowing for far too long, the user may develop a cold in their breathing systems. As a result, they will have to incur an extra piece of health expenses.
  3. The third factor is to consider the ease of operation of the machine. First, all bed fans are simple to install and, as soon as you switch them on, they begin working. If you have selected a great bed fan that seems too complex for you to handle, it is prudent to seek help from professionals. There are several brands and types of bed fans which, create the impression that while there are those that are originally designed to provide an extra feel of the cool air, there are those that tag along with a great sense of class and sleekness that a few people of certain financial prowess can afford.

Summing Up

In conclusion, the merits of using bed fans stretch far and wide-ranging from economic regarding both prices, energy as well as ease of storage as soon as you purchase it from a reliable store.

However, these advantages also, come along with an extra piece of disadvantages that could be detrimental to the health of the user if the right conditions are not put in place.

In most cases, a family with babies who are two years and below should not use a bed fan unless a competent healthcare giver and professional bed fan expert have given the green light.

The reasoning is that children do not possess the same level of immunity and the power to withstand harsh temperatures as opposed to their parents or the typical adult.
